THE SOFT GROUND IMPROVEMENT METHOD WITH DRAIN BOARD HAVING CONSECUTIVE DRAINAGE SPACE

摘要

A soft ground drainage method using a drain board having a continuous drainage space is provided to drain off water from the soft ground smoothly by penetrating a drain board to the soft ground using a drain pressing device. A soft ground drainage method using a drain board having a continuous drainage space for forming a surface layer for moving a drain pressing device or other construction equipment and performing construction work easily and placing a drain board(10) in the soft ground using the drain pressing device, and draining off water from the soft ground comprises the steps of: penetrating a drain board to the inside of a casing coupled to the drain pressing device; connecting the drain board penetrated to the casing with a drain shoe; pressing down the casing to the deep end of the soft ground using the drain pressing device to make the drain shoe and the drain board placed in the soft ground; pulling out the casing only above the ground using a pulling device; and installing many drain shoes and drain boards at the planned intervals, paving soils on the top of the soft ground and applying surcharge pressure.
